Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx FLG{1dS  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm =RM]/O9  
Type: Double Bounces WXf[W  
The '****' denotes a possible internal focus m}beT
~FT_  
RMS is the RMS spot radius on axis at the primary wavelength. cUw$F{|W  
RMS values of 0.00 indicate that an accurate RMS pOB<Bx5t  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is e?o/H  
non-rotationally symmetric or uses non-standard surfaces.
